하지 심부정맥 혈전증의 혈관 내 치료 동안 예방목적의 하대정맥필터 설치 = Prophylactic IVC Filter Placement during Endovascular Treatment of Deep Venous Thrombosis of the Lower Extremities

다국어 초록 (Multilingual Abstract)

Purpose: To evaluate the efficacy of an IVC filter implantation in the prevent of a pulmonary embolism (PE) during endovascular treatment for a deep venous thrombosis (DVT) of the lower extremities.
Materials and Methods: We implanted IVC filters in 43 patients (22 females, 21 males, average age: 63 years) with DVT and who had undergone treatments including thrombolysis, aspiration and mechanical thrombectomy, as well as stent placement. We evaluated the incidence of PE by capturing the thrombus within the IVC filters, as well as the amount of captured thrombus.
Results: New developing PE or aggravating of PE in patients with existing PE was avoided in all patients. No thrombus was evident in the IVC filter of 19 (44%) of the patients, whereas any thrombus was captured in 24 (56%) of the patients. Small amounts of thrombus were captured in 10 patients, whereas large amounts of thrombus were captured in 14 patents within the IVC filter. We performed a retrieval of the IVC filters in 17 patients within an average period of 15.3 days (range 6-45 days).
Conclusion: The captured incidence of migrated thrombus in the IVC filters was high in 56% of cases. As a result, PE was effectively prevented by IVC filters during the interventional treatment of DVT in the lower extremities.

목적: 하지 심부정맥 혈전증의 혈관 내 치료 동안 폐혈전증의 방지를 위한 예방목적 하대정맥필터 설치의 유용성에 대하여 알아보았다.
대상과 방법: 심부정맥 혈전증으로 진단되어 하대정맥필터를 설치한 후 인터벤션 시술-카테터 국소 혈전용해술, 흡입 및 기계적 혈전 제거술, 스텐트 설치를 시행한 43명(여자 22명, 남자 21명, 평균나이 63세)를 대상으로 하였다. 혈전제거술 동안 폐색전증의 발생, 필터 내 혈전의 유무, 혈전의 양을 분석하였다.
결과: 모든 예에서 성공적으로 하대정맥 필터를 설치할 수 있었고 시술 동안 폐색전증의 발생과 확인된 폐색전증의 악화를 방지할 수 있었다. 정맥조영술에서 43명 중 19명(44%)에서 필터 내 혈전이 없었고 24명(56%)에서 혈전이 확인되었다. 24명 중 10명에서 필터 내에 적은 양의 혈전이, 14명에서 많은 양의 혈전이 확인되었다. 17명에서 하대정맥필터를 시술 후 제거하였고 설치 기간은 평균 15.3일(분포 6-45일)이다.
결론: 하지 심부정맥 혈전증에서 혈관 내 인터벤션 시술 동안 하대정맥필터 내 혈전은 56%의 많은 환자에서 확인되었으나 폐색전증은 모든 예에서 차단되어 예방은 효과적이었다.
